Physically you can split a 5mg tablet no problem. I used to take 2.5mg when first starting with Lexapro and did it all the time. I think perhaps it's more to do with the small dosage not being therapeutic (I read most pdocs say you need 10mg at minimum), but initially 2.5 was strong enough for me, so halving the 5mg tabs was what I did.
